摘要：齿轮传动测试机用于测试单级齿轮的传动误差、振动和传动效率。因齿轮传动误差测量对试验机的机械结构精度要求高，除设计制造时提升机械结构精度外，建立被动轴相对于主动轴的空间误差关系和运用误差补偿理论对测量结果进行修正也至关重要。本文通过多体理论和齐次坐标变换关系，建立被动轴相对于主动轴的空间误差数学模型，并根据模型编写空间误差的求解程序，通过输入相应测量结果得到被测齿轮相对于标准齿轮在X，Y，Z三个方向上的误差分量。

Application of Accuracy Analysis Theory in Gear Transmission Testing Machine

Abstract:A gear transmission testing machine is used to measure the transmission error，vibration and noise，and transmission efficiency of single gear.As the transmission error measurement demands highly on the mechanical accuracy，besides improving the precision of mechanical structure，establishing the space error relationship between the driven shaft and the driving shaft and applying the space error to compensate the measurement result are also very important.The multibody theory and the homogeneous coordinate transformation are used to establish the space error model between the driven shaft and the diving shaft，and then a solving program is developed based on the model.The space error components of the measured gear relative to the standard gear in X，Y and Z directions are attained by entering the measurement result into the program.
